We’re Lodgewick ADU Builders, and we build accessory dwelling units – second homes on your existing lot – across Daly City. The homes here are mostly mid-century stucco builds from the Westlake and Broadmoor developments, and Daly City’s hillside lots, persistent fog, and strict hillside development rules change how an ADU gets planned, permitted, and built. If you’re weighing a detached ADU, a garage conversion, or an addition, call (707) 760-0502 and we’ll give you a written price before any work starts.
Why Daly City Homes Are Different
Daly City’s housing stock doesn’t behave like the flatland suburbs a few miles south. Many homes in the Westlake and Broadmoor tracts were built in the 1950s and 60s on steep, narrow hillside lots. That means ADU design has to account for hillside foundations, limited rear yards, and street access tight enough that a crane or a concrete truck isn’t always an option. On a hillside lot off Skyline Boulevard or in the St. Francis Heights area, a detached ADU almost always requires a soils report and a graded foundation plan, and the city’s hillside development rules add plan-check time to any project. The payoff is real though – hillside ADUs in Daly City hold their value well because they add square footage to properties where the buildable footprint is scarce.
Then there’s the fog. Daly City’s marine layer sits over the city much of the summer, and that cool, damp air drives material choices. We spec moisture-resilient siding, careful flashing around windows and doors, and ventilation designed for a house that rarely gets to fully dry out. That’s true whether we’re fixing an exterior on a garage conversion or building an attached ADU. Add in aging utility connections on many of these mid-century lots, and proper planning matters more than it does in a newer subdivision. The Kingswell Way is how we handle all of it: say the price before the work, show up in the window we gave you, leave the job site cleaner than we found it, and put the guarantee in writing.
Our Main Daly City Services
Most Daly City homeowners call us about one of three things: adding square footage to their existing home, converting an underused garage into living space, or building a detached or attached ADU from the ground up. Each has its own page with details, pricing, and what the job looks like on a Daly City hillside lot.
Home Addition Contractor in Daly City
A home addition on a Daly City hillside lot is a different job than one on flat ground. Your builder has to work around slope setbacks, limited street access, and a lot of stucco that has to match what’s already there. We plan additions that handle the damp coastal air and work with your existing foundation, not against it. Whether you’re adding a primary suite off the back of a Broadmoor rancher or expanding a kitchen in Westlake, we write the price before we start and put the guarantee on paper.

Garage Conversion Contractor in Daly City
Daly City has a lot of attached garages on small lots, and converting one into living space is often the fastest way to add a rental unit or an in-law suite without new foundation work. But garage conversions here come with their own problems: moisture from the fog, older slab floors, and utility panels that need upgrading to handle the new load. We handle the whole conversion – framing, insulation, drywall, electrical, plumbing, and whatever the permit requires – and we put the price in writing first.

ADU Builders in Daly City
Daly City’s density bonuses and hillside rules make attached ADUs the more common path here, especially the “Daly City special” – a tall, narrow unit tucked against the uphill side of the house, clad in matching stucco so it reads as part of the original structure. Detached ADUs are possible too, but on steep lots they take more engineering and cost more per square foot. Either way, we’ll walk your specific lot, tell you what’s buildable, and hand you a written price. ADU Builders in Daly City

On a Daly City hillside lot, the biggest price movers are foundation work and street access. If the site can’t take a standard concrete pump or the slope requires a retained cut, the price reflects that engineering, not a surprise at the door. That’s why we give every homeowner a written price before any work starts – no price changes at the door, ever.

On most steep Daly City lots, yes. Any detached ADU or significant addition on a sloped lot in the hillside zoning districts typically needs a soils report and a graded foundation plan as part of the permit package. We handle that engineering as part of the written quote, so you won’t get hit with a surprise change order halfway through plan check. Call us for a free estimate and we’ll tell you exactly what your specific lot needs.
It does. The marine layer keeps exterior surfaces damp for weeks at a time, which is why we spec moisture-resilient siding and careful window flashing on every Daly City project. It’s a small planning step that prevents big problems later. If you’re weighing materials or a prefab unit, call (707) 760-0502 and we’ll walk you through what holds up out here.
